TI545/TI555 Simatic PLC

Programmable Logic Controllers or PLCs, are one the several major categories of repair that Control System Labs can complete. In our 50+ years of repairing industrial electronic controls, we've developed information and data on these types of repairs to assist our expert technicians in troubleshooting repairs for our customers.

These particular PLCs are designed to perform control functions such as monitoring inputs, making decisions based on programmed logic, and controlling outputs.

Some of the common functions of these PLCs include:

• Input/output control

•  Programmed logic

•  Communication

•  Data logging

Common failures of these PLCs can include problems with the electronic components, such as faulty power supplies or defective circuit boards. Other common failures can include communication failures, software errors, and programming issues. For example, the Siemens Simatic PLCs can experience problems with communication due to issues with the Ethernet or Profibus connections, while the Texas Instruments TI545/TI555 Simatic PLCs can experience problems with software errors and programming issues.
